Rear Coil-over assemblies:

We have been building and selling these kits forseveral years now, but we have never put them on the website. We startwith a Ground Control designed rear lower shock mount. Machined fromhigh carbon steel, and using a grade 8 bolt, this rear lower mount isdesigned to carry the weight of the car after springs are added to theshock. We utilize a Koni SINGLE ADJUSTABLE monotube rear shock, adjustable for rebounddamping. This shock is available in our standard default damping forstandard width cars, or heavier damping for wider cars with higherspring rates. The Koni shock is mounted inverted for less unsprungweight, and features the exclusive GC coil-over hardware withsingle-locking sleeve and and your choice of Eibach race spring. Thesame kit is used to supplement rear torsion bars (PCA Stock Class) orby choosing a different spring rate, the rear torsion bars can beremoved completely. If you are considering over 700 pound rear springs,we recommend fabricating a double shear rear lower mount to supplementour lower mount.

924 and early 944 (steel arm) is in development and will be the same price.

All Ground Control products carry a lifetime guarantee against defects when
installed and maintained correctly. We strongly recommend that all of our products be installed by a competent, qualified mechanic.
